2. Description of the Related Art Lithium secondary batteries, which have been actively researched and developed in recent years, have different charge and discharge voltages depending on the electrodes used.
Battery characteristics such as charge / discharge cycle life characteristics and storage characteristics are greatly influenced. Therefore, the battery characteristics have been improved and improved by improving the active material used for the electrode.

It is known that when a battery is manufactured using lithium metal as a negative electrode active material, a battery having a high energy density per weight and volume can be obtained.
In this case, on the negative electrode, lithium is deposited by charging and lithium is dissolved by discharging. By repeatedly charging and discharging this battery, precipitation and dissolution of lithium on the negative electrode are repeated. This causes a disadvantage that lithium is deposited in the form of dendrite (dendritic) on the negative electrode. As a result, there is a problem that an internal short circuit occurs.

Therefore, conventionally, by using aluminum, silicon, tin or the like which is electrochemically alloyed with lithium during charging as a negative electrode active material, a lithium secondary battery in which the above dendrite-like deposition of lithium is suppressed. Is proposed. These are, for example, Sol
id State Ionics, 113-115, p
57 (1998). Among these aluminum, silicon, tin, etc., since silicon has a particularly large theoretical capacity, it is a promising material as a negative electrode active material of a battery showing a high capacity.

The Applicant has used silicon as a negative electrode active material,
As a lithium secondary battery electrode showing good charge / discharge cycle characteristics, a method such as CVD or sputtering in which a raw material is released into the gas phase and supplied, is used to form a microcrystalline silicon layer or a non-crystalline silicon layer on the current collector. An electrode for a lithium secondary battery having a crystalline silicon layer is proposed in International Publication WO01 / 29912 and the like.
